The nth term in the Fibonacci series is printed at the conclusion of the program.
What is a Fibonacci sequence?The Fibonacci numbers, also known as Fₙ, are a set of numbers in mathematics where each number is the sum of the two numbers before it. Although some authors omit the initial terms and begin the sequence from 1 and 1 or from 1 and 2, the sequence typically starts from 0 and 1.So, until a condition is satisfied, recursions involve calling a function from within a function.
The necessary function, which uses comments to describe each line, is as follows:
//This defines the function
public static int fibonacci(int n) {
//The function returns -1, if n is negative
if(n<0){
return -1;}
//The function returns the value of n, if n is 0 or 1
if(n==0||n==1){
return n;}
//If otherwise
else{
//The function returns the nth term of the Fibonacci series
return fibonacci(n-1)+fibonacci(n-2);
}
}
Therefore, the nth term in the Fibonacci series is printed at the conclusion of the program.

The correct question is given below:
The Fibonacci sequence begins with 0 and then 1 follows. All subsequent values are the sum of the previous two, for example: 0, 1, 1, 2, 3, 5, 8, 13. Complete the fibonacci() method, which takes in an index, n, and returns the nth value in the sequence. Any negative index values should return -1.
Ex: If the input is: 7
the out put is :fibonacci(7) is 13

Avani and her children went into a grocery store and will buy peaches and mangos.
Each peach costs $0.75 and each mango costs $1.75. Avani has a total of $15 to spend
on peaches and mangos. Write an inequality that would represent the possible values
for the number of peaches purchased, p, and the number of mangos purchased, m.
The inequality which represents the possible values for the number of peaches and mangos purchased will be;
⇒ $0.75p + $1.75m = $15
What is Inequality?
A relation by which we can compare two or more mathematical expression is called an inequality.
Given that;
Avni and her children went into a grocery store and will buy peaches and mangos.
Each peach costs $0.75 and each mango costs $1.75.
And, Avni has a total of $15 to spend on peaches and mangos.
Now,
Let number of peaches purchased = p
And, Number of Mangos purchased = m
Since, Each peach costs $0.75.
Hence, Total cost of peaches purchased = $0.75p
And, Each mango costs $1.75.
Hence, Total cost of mangos purchased = $1.75m
Since, Avani has a total of $15 to spend on peaches and mangos.
So, An inequality that would represent the possible values of peaches and mangos will be;
⇒ $0.75p + $1.75m = $15
Thus, The inequality which represents the possible values for the number of peaches and mangos purchased will be;
⇒ $0.75p + $1.75m = $15

A line is drawn through (-7, 11) and (8,-9). The equation
y-11 = -4/3(x + 7) is written to represent the line. Which
equations also represent the line? Check all that apply.
Answer:
[tex]\textsf{Slope-intercept form}: \quad y=-\dfrac{4}{3}x+\dfrac{5}{3}[/tex]
[tex]\textsf{Standard form}: \quad 4x+3y=5[/tex]
Step-by-step explanation:
Given linear equation:
[tex]y-11=-\dfrac{4}{3}(x+7)[/tex]
The given linear equation is point-slope form.
[tex]\boxed{\begin{minipage}{3.7cm}\underline{Slope-intercept form}\\\\$y=mx+b$\\\\where $m$ is the slope\\ and $b$ is the $y$-intercept.\\\end{minipage}}[/tex]
To write the equation in slope-intercept form, isolate y:
[tex]\implies y-11=-\dfrac{4}{3}(x+7)[/tex]
[tex]\implies y-11=-\dfrac{4}{3}x-\dfrac{28}{3}[/tex]
[tex]\implies y-11+11=-\dfrac{4}{3}x-\dfrac{28}{3}+11[/tex]
[tex]\implies y=-\dfrac{4}{3}x+\dfrac{5}{3}[/tex]
[tex]\boxed{\begin{minipage}{5.4 cm}\underline{Standard form}\\\\$Ax+By=C$\\\\where $A, B$ and $C$ are constants and $A$ must be positive.\\\end{minipage}}[/tex]
To write the equation in standard form, eliminate the fraction, bring the terms in x and y to the left of the equation, and the constants to the right:
[tex]\implies y-11=-\dfrac{4}{3}(x+7)[/tex]
[tex]\implies (y-11) \cdot 3=-\dfrac{4}{3}(x+7) \cdot 3[/tex]
[tex]\implies 3y-33=-4(x+7)[/tex]
[tex]\implies 3y-33=-4x-28[/tex]
[tex]\implies 3y-33+4x=-4x-28+4x[/tex]
[tex]\implies 3y-33+4x=-28[/tex]
[tex]\implies 3y-33+4x+33=-28+33[/tex]

Carol has 1\frac{5}{8} cups of yogurt to make smoothies. Each smoothie uses \frac{1}{3} cup of yogurt.
What is the maximum number of smoothies that Carol can make with yogurt?
Carol can make a maximum of 4 smoothies with the available yoghurt
Cups of yoghurt Carol has for making smoothies = 1 5/8 cups
Yoghurt Carol has in improper fractions = 13/8 cups
Cup of yoghurt used to make smoothie = 1/3 cups
Fractions: A numerical value that designates a portion of a whole is used to represent fractions. A fraction is a component or section taken from a whole, which can be any number, a certain amount, or an object.
Number of smoothies Carol can make = Total available yoghurt with Carol/Yoghurt used to make a smoothie
= (13/8)/(1/3)
= 39/8
Converting the fraction into a mixed fraction we get: 4 7/8 smoothies
So, she can make 4 cups of smoothie

Based on the dilation, the scale factor of dilation of the point is 1/3
What is dilation?Dilation involves enlarging or reducing the side length of a shape to create another shape by a constant scale factor, where the scale factor does not equal one.
How to determine the scale factor of dilation?From the question, we have the following parameters
Dilation rule: Do,k
Point = (9, 6)
Image = (3, 2)
As a general rule of dilation, the following are the properties of a scaled copy of another figure
If the scale factor is greater than 1, the side lengths would be greater than the original figureIf the scale factor is less than 1, the side lengths would be less than the original figureThe side lengths may or may not be whole numbersUsing the above as a guide, the scaled factor is calculated as
Scaled factor = Image/Poins
This gives
Scaled factor, k = (3, 2)/(9, 6)
This gives
Scaled factor, k = 1/3
Hence, the scale factor is 1/3

A circular pond has a diameter of 15 feet which expression can be used to find the circumference in feet 
The expression used for finding the circumference of the circular pond is; C = 2π(d/2) feet.
What is defined as the circumference?The circumference of the circle, also known as the perimeter of the circle, is the measurement of the circle's boundary. The area of a circle, on the other hand, defines the region it occupies. If we expand a circle and draw a straight line through it, the length of the line is the circumference. It is typically measured in units such as centimeters or meters.For the given question;
Let 'd' be the diameter of the circular pond.
The diameter of the pond = 15 feet.
Let 'C' be the circumference of the circle;
The, the formula for finding the circumference of the circle is;
C = 2π(d/2) feet
For, d = 15 feet
C = 2π(15/2) feet
Take π = 3.14
C = 2×3.14×(15/2) feet
C = 47.1 feet
Thus, the circumference of the circular pond is found as 47.1 feet.

What is Algebraic expression ?
Algebraic expressions are the idea of expressing numbers using letters or alphabets without specifying their actual values. The basics of algebra taught us how to express an unknown value using letters such as x, y, z, etc. These letters are called here as variables. An algebraic expression can be a combination of both variables and constants. Any value that is placed before and multiplied by a variable is a coefficient.
let the integer be x

Suppose the domain of f is ( -1, 1).
Define the fucnction g by g(x)=f([tex]\frac{x+1}{x-1}[/tex]).
What is the domain of g?
If the domain of f is ( -1, 1), then the function g defined by g(x) = f((x + 1)/(x - 1)) has a domain of; (-2, 0)
What is the domain of the function?The domain of a function refers to the set of all possible intput values that make the function possible.
Now, we are given the function;
g(x) = f((x + 1)/(x - 1))
The domain would be a set of real numbers excluding 1 because at x = 1, the function is undefined.
Since the domain of f(x) is -1 < x < 1 ,
Then the domain of f(x + 1) is -1 < x + 1 < 1 .
domain of -1 < x + 1 < 1 will simplify to -2 < x < 0
Thus, we can say that the domain of f(x + 1) is (-2, 0).
Thus;
g(x) = f(x + 1) and as such, the domain of g(x) is (-2, 0) .
